Design of the cables
ƒ The cables used must comply with the approvals required for the location (e.g. UL).
ƒ It is imperative to comply with the regulations concerning minimum cross-sections
of PE conductors. The cross-section of the PE conductor must be at least as large as
the cross-section of the power connections.
ƒ
The effectiveness of a shielded cable is reached by:
– Providing a good shield connection through large-surface shield contact.
– Using only braided shields with low shield resistance made of tin-plated or
nickel-plated copper braid.
– Using braided shields with an overlap rate > 70 % and an overlap angle of 90 °.
– Keeping unshielded cable ends as short as possible.
Use system cables or shielded cables for these connections:
ƒ Motor
ƒ Motor holding brake (connected to optional motor brake control)
ƒ Motor temperature monitoring
ƒ Analog signals (inputs and outputs)
ƒ System bus CAN
ƒ
Resolver
ƒ Encoder
The following connections need not be shielded:
ƒ Mains
ƒ 24 V supply
ƒ Digital signals (inputs and outputs)
